I need to measure my chambers as well. I have a Oly and a Douglas barrel, and they will both chamber brass far longer than 1.365". What was the best method to measure chamber length without specialized tools again?
I had my first case length problem yesterday. The mouth was looking funny. like it had been flattened/stretched out. A quick measurement showed I was at 1.405" All the other cases were fine and of under 1.400". I am sure that is the length of my chamber.
